SPECIFCATION forming part of Letters Patent No. 414,486, dated November 5, 1889.

Application tiled February 15,1889. Serial No. 299,978. (No model.)

To all whom it may concern:

Be it known that l, WILLIAn l1. Boor- MAN, a resident of 7Waterford, in the county of Saratoga and State of New York, have invented certain new and useful Improvements in Hydrants; and I do hereby declare that the following is a full, clear, and exact description of the invention, that will 'enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of thisspecitication.

Simi-lar letters refer to similar parts in the several figures.

Myinvention relates to improvements in hydrants, and more particularly to that class known as tire-plugsf7 and it consists of the novel construction and combination of parts hereinafter described, and pointed out in the claims. y

Figure l of the drawings is a vertical central section of my improved hydrant, showing the main valve open and the drip-valve closed. Fig. 2 represents in elevation and plan views the follower-plate T detached. Fig. 3 shows similar views of the stay-plate M. Fig. a is a horizontal section taken on the broken line y y in Fig. 1l. Fig. 5 shows in elevation and plan an adjustable collar for supporting the mechanism for operating the drip-valve. Fig. 6 is a central longitudinal section of the lower part of the tubular post, the upper portion being broken away. Fig. 7 is a top plan or end view of the post detached. Fig. S is a horizontal section taken on the broken line :e n: in Fig. '11. Fig. 9 shows in elevation and plan the detachable stem-nut and nut-supporting legs. Fig. lOis a horizontal section taken on the broken line e e in Fig. 1l. Fig. 11 is a vertical central section similar to that shown in Fig. l, showing the main valve closed and the dripvalve open.

B represents the stand-pipe, which maybe of any well-known form. The lower flanged end of the pipe is secured by screws B6 to the bottom casting B', having an inlet H leading through valved passage-way H into the pipe. The upper end of the pipe is closed by cap B2, having astufngbox C for the passage of 'rated stay-plate M.

the valve-stem S. The cap is secured. to the upper end of the pipe bythe bolts B3, passed through the ange B4- on the cap and flange B5 on the pipe. The upper end of the pipe is also provided with an outlet N, which may ing end adapted to receive a soelet-wrench or other mechanism for imparting to the stem a rotary movement. The lower end of the stem terminates in a circular head or disk P, adapted to rotate in a corresponding socket located centrally of the plug Gr and opening upward. The plug is adapted to fit the annular seat Q. In operating the hydrant the stem is rotated in one direction to open the valve and the opposite direction to close it, the rotary movement causing the screw to travel up and down through the stem-nut and carry with it the plug. The stem nut is held in position over the valveopening by means of the tubular post P, the lower end of which is adapted to `re ceive and fit. the nut or a rectangular head K thereon. the nut to the upper end of the stand-pipe, and is held in place upon the nut by means of a centrallyperforated follower-plate T, bolted, as by bolts E, to the centrallyperfo- The latter plate is held in place by the lugs E, projecting interiorly from the upper end Aot' the stand-pipe, with which lugs the plate is brought into engagement by revolving the ends thereunder after it has been slipped onto the post or tube P and passed below the lugs, the post entering its central aperture,which it lits loosely. The central aperture of the follower-plate is adapted to receive the valvestem, but not large enough to receive the post. This plate therefore engages with the post and forces it down upon the stem-nut with a degree of pressure which may be varied as desired by means of the screw-bolts E and their nuts. The nut-supporting legs are thus forced The post extends upward from y I Oi) tightly upon the bottom casting, and the nut l thereon.

held firmly in position and enabled to force the valve-plug and stem up and down to unseat and seat the valve-plug the same as though the nut were rigidly attached to the bottom-casting.

When it is desired to remove the stem-nut, stem, and valve-plug for any purpose, it is only necessary to detach the cap B2 and plates T and M, and then lift them out of the standpipe by means of the stem.

I provide the upper end edge of the tubular post with one or more spurs or lugs P2, adapted to enter and lit corresponding notches or depressions in the lower side of the follower-plate to prevent the post from rotating, and the lower end of the post having a rectangular socket K, adapted to receive and fit the rectangular head K on the nut, the latter is positively secured to resist any rotary strain induced by the rotary movements of the threaded stem within the nut. The post incloses the stem, which is rotary within it, and also serves to support the regulating mechanism for the dri p-valve G. This valve is adapted to close the drip-passage G2, leading through the bottom casting exteriorly of the hydrant, and is provided with a stem S', leading to the operating-lever L, which is a lever of the first class fulcrumed uponthe pin F, supported by the ears D, projecting from the collar O, adapted to be slipped upon the post and movable longitudinally The collar is provided with a setscrew J, by which it can be adjustably secured at any desired point on the post. One end of the lever is pivotally connected with the upper end of the drip-valve stem, as by pivot I, and the other end passes through the slot P3 in the post to engage with the edge walls on the main-valve stem formed by the annular groove R. As the main-valve stem moves upward to open the main valve the lower edge wall of tlie'groove R engages with the'lever L to depress the stem S and close the drip-valve, and when the main-valve stern is given a downward movement to close t-he main valve the upper wall of the groove engages with the lever to open the drip-valve. The upper part of the valve-stern S may be given a slightly-increased diameter to cause the upper edge wall formed by groove R to project beyond the lower edge wall, thereby increasing the upward movement of the dripvalve and insuring a positive engagement of by threading the upper end of the stein proper,

and then screwing the same into a corre- Y spondingly-tapped head W, which head is pivoted to the lever L, as shown. It is obvious that if the stem Ais rotated in one direction it will be forced farther into the head W and shortened, and that it can be correspondingly lengthened by rotating it in the opposite direction.

The height of the collar can be adjusted by set-screw J, as before explained, so as to secure the proper and desired engagement of the lever L with the lever-actuating edge walls formed by groove R.

Vhat I claim as new, and desire to secure by Letters Patent, is-

1. In a hydrant, the combination, with a valve and valve-stem, of a detachable stemnut provided with a plurality of supportinglegs, a tubular post resting upon such legs and engaging the nut at its lower end, and an adjustable post-support `secured to the upper end of the hydrant and bearing against the top of the post, substantially as described.

2. In ahydrant havinga drip-opening and annularly grooved vertically reciprocatory stem for the main valve, the combinatiomwith the edge walls formed by the groove in the main stem, of the drip-valve and stem and a drip-stem-actuating lever -fulcrumed upon a xed support, having one end of the lever pivotally connected with such drip-valve stem and the other end alternately engageable with substantially as described.

3. In a hydrant having a drip-opening, an

annularly grooved vertically reciprocatory stem for the main valve and a tubular steininclosing post, the combination, with the edge walls formed by the .groove in the main stem, of a drip-valve and stern, a drip-stem-actuating lever having one end of the lever piv-' otally connected with such drip-valve stem,

and a lever-supporting collar vertically ad-Y justable upon such post, whereby the free end of the lever is supported in a position to alternately engage with the edge walls formed by the annular groove upon the main stem, substantially as described.
